PATENT OFFICE.

.AII'GI'ILLI IPURI'URA, 0F LAWRENCE, MASSACHUSETTS SHOE INSOLE.

Application led March 14, 1928. Serial No. 261,562.

This invention -relates vto an insole for a shoe,the general object of the invention being to so form the insole that it will act to correct various forms of foot trouble, such as swollen arches, fallen arches, rlieumatism in the feet,

Weak and flat feet and weakened arches, the

.device eliminating the use orn arch supports which are awkward and cumbersome and difficult to properly position in a shoe, the present device forming a part of the shoe.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or ,t

c orresponding parts throughout the several views, and in which j Figure -1 is a side viewshowing the improved insole placed in a shoe.

Figure 2 is a plan viewv of the insole.

Figure?) is asection on lin'e 3 3 of Figure 1. l Figure4' is -'a section on line 4 4 of Fignrc l. H

Fig-ure 5 is a section on line`5-45 of j As shown in-Figure 1, the improved insole l forms a partof the shoe A. The insole has a sinallexternal flange 2'which extends from the center of the heel toa point just behindv the base ofthe fifth metatarsal bone and a large internal flange 3 which'extends from a pointadjacent the end ofl the heel to a point 4in close proximity 'to the base of the big toe and this flange extends upwardly to a point well above the prominent bones on the inner side ot the instep, thetop of the flange terminating about -half an linch below the malleolus. This fla `e 3 iscurved to lit the instep -y at the inner si e of the foot, as shown in the drawings. f

. A projection 4 is formedon the central portion of the insole, this projection being of substantially wedge shape with its large rounded end locatedl at the front adjacent the base of the toes and its small end terminating adjacentthe front part of the heel. This projection is formed by a depression pressed into the under part of the insole. This depression will act against the inner cuneiform bones. The instep portion of the insole, with the flanges and .the projection et are hardened by the well known water process so that these portions of' the insole will give a lirm support to the parts of' the foot engaged thereby.

Thus it will be seen that I have provided an insole for a shoe which-takes the place of an arch support and forms part of the shoe and itsuse will correct flat feet, fallen and swollen arches, weak ankles, rheumatism of the feet, etc., and is a protection for the astragalonavicular join-t.l

It is thought from the foregoing description that the advantages and novel features of my'invention will be readily apparent. It is to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that siich changes fall within the scope of the appended claim.

What I claim is A shoe having its insole formed with an interior'flange of' small height and extending froma point at the cent-cr of the heel to a point just behind the base of the lifth metatarsal bone and an internal Hange extending from a point adjacent the end of the hcelto A a point adjacent` the base ofthe big toe, said inner flange being of curved shape in cross section and extending upwardly to a point slightly below the malleoln's, a edge-shaped projectionat the center of the insole with its large end rounded and located at the front end of the instep portion -and its small end located a slight distance from the front portion of the heel. the instep portion of the insole, with theflanges and projection, being hardened.

In testimony whereof-I aflix my signature.

ANGELO PURPURA.
